Weeds compete with cultivated plants for nutrients, water, light and space. Weeds should be destroyed before they flower and disperse seeds which will lead to a greatly magnified problem. Weeds can be controlled in many ways. The most common methods are:

Hand removal or hoeing: if this method is employed the weeds toor system must be removed as the weed may re-grow.

Chemical control: Spraying weed killers can be classified into many different categories including pre-emergent, post-emergent, contact weed killers and systemic weed killers depending on the method and timing of the application.

Please use non-residual herbicide as they will not leave any harmful residue for other plants. If spraying nearby waterways, bioactive Roundup should be used as they are harmless to aquatic fauna.
